With teams keen to limit the 2014 race schedule to 20 races, Formula One's chief executive had identified India and Korea as the most likely to go.

"I think there is a consensus about doing 20 races," Mercedes' Toto Wolff said in Hungary, following meetings with his fellow F1 chiefs. "Anything more and you need to ramp up the organization. So let's stick to 20."

The main problem in India is a tax issue, with the government insisting teams and drivers should be taxed at a full rate on their high incomes.
